[Elecraft] KPA1500 ... ATU tune cycle must be initiated manually since key line interrupter is installed

[Don Butler]

I’m just getting to know my new KPA1500 and am having a ball doing so …. it is a gem!    one minor problem:  I’m using the key line interrupter in the Aux cable since I am keying through a microHam MK2R+ (the K3S/KPA1500 is one of two radios connected through the MK2R+ ….. so the key line must now run from K3 to MK2R+ to KPA1500).   Without the direct keyline connection between K3 and amp I must manually key the K3 to initiate an ATU tune cycle  ….  I suspect that the same problem would exist if I were using a KPA500  …. How have KPA500 users been working around this?
